Optimization of Conditions for Processing of Lead–Zinc Ores Enrichment Tailings of East Kazakhstan

This article presents the results of studies of a low-waste technology for processing enrichment tailings using a combined enrichment–hydrometallurgical method. After washing the enrichment tailings from harmful products and reducing their size, multi-stage flotation of the crushed material of the e...
